Integrally-replaced U-shaped belt corrugated energy dissipation part damper

Abstract

The invention relates to an integrally-replaced U-shaped belt corrugated energy dissipation part damper, and belongs to the technical field of civil engineering energy dissipation and shock absorption. The metal damper is composed of a plurality of U-shaped energy dissipation parts, double-layer corrugated energy dissipation parts and two cover plates. The metal damper is provided based on the design concepts of multi-directional energy dissipation, improvement of shear bearing capacity, inhibition of out-of-plane buckling, improvement of structural rigidity, cooperative work of multiple shearenergy dissipation mechanisms, a double-insurance mechanism and the like, and the limitation of a traditional metal damper is broken through. The U-shaped energy dissipation units are connected in parallel, so that the multidirectional energy dissipation of the damper is effectively realized. Through a reasonable design, the problem that the damper is not prone to generating plastic energy dissipation and needs to dissipate energy of a main body structure in a small earthquake is solved. All the components enter plasticity during a large earthquake, so that the U-shaped energy consumption piece and the double-layer waveform energy consumption piece consume energy together, a double-insurance mechanism is formed, the shear bearing capacity is improved, the energy consumption performance isstable, and only the energy consumption components need to be replaced after the earthquake to recover the function; the metal damper is easy and convenient to replace, obvious in economic benefit and capable of being effectively combined with the support and providing lateral force for the support.

Description

technical field [0001] This patent relates to an integrally replaceable U-shaped damper with wave-shaped energy-dissipating parts, which can be used to control the seismic response of structures, thereby improving the seismic performance of the main structure, and belongs to the technical field of energy dissipation and shock absorption in civil engineering. Background technique [0002] Earthquake is a natural disaster, which is sudden and destructive. The occurrence of strong earthquakes may cause huge economic losses and casualties. my country is an earthquake-prone country, and most of the first-tier cities are in the earthquake zone. With the acceleration of the development of our country, the urban population and facilities are becoming more and more concentrated, resulting in more and more high-rise buildings, the traditional anti-seismic strategy is no longer applicable, and the research of new energy dissipation dampers is imperative.
